The brown bullhead is a catfish with a sharp, venomous spine on its fins. It lives in lakes, ponds and slow streams across North America, and it is important to the Ojibwe people, who see it as one of their clan symbols.1

Native to eastern North America, from Nova Scotia to Alabama and across the Great Lakes and Mississippi basins; also stocked widely elsewhere in North America, Europe, Chile and New Zealand.1

Hoe om dit te herken

Dark brown-green back that becomes lighter green and yellow towards the belly, which is off-white or cream1
Dark brown-black speckles over the whole body1
No scales1
Eight barbels (whisker-like feelers) around the mouth, with black to yellowish brown barbels on the chin1
Adults usually measure 20 to 50 cm and weigh 0.5 to 3.6 kg1

Word dikwels verwar met: The black bullhead and yellow bullhead are similar. The brown bullhead has yellow-black chin barbels, no pale bar at the base of the tail (which the black bullhead has), and 21 to 24 rays in its anal fin. The flathead catfish lacks the brown bullhead's tooth patch on the upper jaw.1

Gifkrag

Giftige stekels

Skerp stekels dra die gif. Dit maak seer as jy daarop trap of dit gryp.

Wat doen sy gif as dit byt of steek?

When attacked, the bullhead stiffens the sharp spine on the front edge of its dorsal and pectoral fins. While doing this, it releases venom that stings and burns the predator.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

Its fin spines can sting and burn, which is its main defence against predators. Treat any caught fish with care and avoid handling its spines.1

Wat doen dit as dit bang is?

When attacked, it stiffens its fin spines to make it harder for a predator to swallow it, and releases venom to sting and burn.1

As sy stekels jou steek

Sit die wond in warm water, so warm as wat die persoon kan verdra sonder om te brand (toets dit met jou eie hand), vir 30 tot 90 minute. Kry mediese hulp, veral vir klipvisse en pylsterte.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As sy stekels jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

It can survive very low oxygen levels, down to 0.2 ppm, and even heavily polluted water.1

Its spines can produce venom, which is unusual for a catfish species that is otherwise common and widely eaten.1

The brown bullhead is one of six beings in Ojibwe tradition that came out of the sea to form the original clans.1

Both males and females are known to eat their own eggs at times.1
